marking it as release-able, attaching the same version number that is
attached to other binaries such as `polkadot` and `polkadot-parachain`.

I have more thoughts about the version number, though. The chain-spec
builder is mainly a user of the `sp-genesis-builder` api. So the
versioning should be such that it helps users know give a version of
`sp-genesis-builder` in their runtime, which version of
`chain-spec-builder` should they use?

With this, we can possibly alter the version number to always match
`sp-genesis-builder`.
